[Steem] [0.19.12] Logging problem and unexpected char 108 in log-appender

Project Information

Repository: https://github.com/steemit/steem
Project Name: Steem
Affected versions: 0.19.11/.12

Expected behavior

When enabled in the configuration file, the steemd process should allow logging to file.

Actual behavior

Logging to file is not happening. Upon starting steemd, an error is given:
Error parsing logging config. Parse Error:Unexpected char '108' in "log-appender"

Other related bugs:

• steemd file logging isn't working in v0.19.11/.12 (it worked in 0.19.10).
• cli_wallet says Logging RPC to file: logs/rpc/rpc.log but nothing is happening there.
• Logging level is not obeyed, debug/warn/info all show the same things in the console log.

How to reproduce

Start or replay the steemd process. Check the console log for the error feedback.
